Abstract

Abstract : BREAKING THE RULE! N -(2, 6-diisopropylphenyl) α-diimines, known to be robust ligands in coordination chemistry, convert into quinoxalinium cations by reaction with WCl6 in mild conditions. Abstract : The full potential of a high valent metal chloride as both a chlorinating and an oxidative agent was explored by allowing WCl6 to react with N -(2, 6-diisopropylphenyl) α-diimines, in CH2 Cl2 at room temperature. These α-diimines underwent unprecedented conversion to quinoxalinium cations via intramolecular C–N coupling.
